Engine-Oil Specifications
Oil Type: Detergent oil (API service SJ or higher)
Crankcase Capacity: with a filter change, 1.8 L (61 fl oz); with no filter change, 1.6 L (54 fl oz)
Viscosity: See table below
Checking the Engine-Oil Level
-
Park the machine on a level surface, engage the parking brake (if equipped), and lower the loader arms.
-
Shut off the engine and remove the key.
-
Clean the area around the oil dipstick (Figure 23).
-
Pull out the dipstick and wipe the metal end clean (Figure 23).
-
Slide the dipstick fully into the dipstick tube (Figure 23).
-
Pull the dipstick out and look at the metal end.
-
If the oil level is low, clean the area around the oil-fill cap and remove the cap (Figure 23).
-
Slowly pour only enough oil into the valve cover to raise the level to the F (Full) mark.
Important: Do not overfill the crankcase with oil because the engine may be damaged.
-
Replace the fill cap and dipstick.
Changing the Engine Oil and Filter
-
Start the engine and let it run for 5 minutes.
Note: This warms the oil so that it drains better.
-
Park the machine so that the drain side is slightly lower than the opposite side to ensure that the oil drains completely.
-
Lower the loader arms, chock the wheels or engage the parking brake (if equipped), shut off the engine, and remove the key.
-
Place one end of a hose on the drain valve and the other end in a pan (Figure 24).
-
Open the drain valve by turning it counterclockwise, pulling out as you turn it (Figure 24).
-
When the oil has drained completely, close the drain valve and remove the hose.
Note: Dispose of the used oil at a certified recycling center.
-
Remove the old filter and wipe the filter adapter (Figure 25) gasket surface.
-
Pour new oil of the proper type in through the center hole of the filter. Stop pouring when the oil reaches the bottom of the threads.
-
Allow 1 to 2 minutes for the oil to be absorbed by filter material, then pour off the excess oil.
-
Apply a thin coat of new oil to the rubber gasket on the replacement filter (Figure 25).
-
Install the replacement oil filter to the filter adapter. Turn the oil filter clockwise until the rubber gasket contacts the filter adapter, then tighten the filter an additional 1/2 turn (Figure 25).
-
Remove the fill cap (Figure 23) and slowly pour approximately 80% of the specified amount of oil in through the valve cover.
-
Check the oil level.
-
Slowly add additional oil to bring the level to the F (full) mark on the dipstick.
-
Install the fill cap.
Servicing the Spark Plug(s)
Maintenance Service Interval | Maintenance Procedure |
---|---|
Every 200 hours |
|
Every 500 hours |
|
Ensure that the air gap between the center and side electrodes is correct before installing each spark plug. Use a spark-plug wrench for removing and installing each spark plug and a gapping tool/feeler gauge to check and adjust the air gap. Install new spark plugs if necessary.
Type: Champion XC12YC or equivalent.
Air Gap: 0.75 mm (0.03 inch)
Removing the Spark Plug
-
Park the machine on a level surface, engage the parking brake (if equipped), and lower the loader arms.
-
Shut off the engine, remove the key, and allow the engine to cool.
-
Clean the area around the base of the plug(s) to keep dirt and debris out of the engine.
-
Remove the spark plug(s) as shown in Figure 26.
Checking the Spark Plug
Important: Do not clean the spark plug(s). Always replace the spark plug(s) when it has a black coating, worn electrodes, an oily film, or cracks.
If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty.
Set the gap to 0.75 mm (0.03 inch).

Hydraulic System Maintenance
Hydraulic System Safety
-
Seek immediate medical attention if fluid is injected into skin. Injected fluid must be surgically removed within a few hours by a doctor.
-
Ensure that all hydraulic-fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system.
-
Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.
-
Use cardboard or paper to find hydraulic leaks.
-
Safely relieve all pressure in the hydraulic system before performing any work on the hydraulic system.
Relieving Hydraulic Pressure
To relieve hydraulic pressure while the engine is on, disengage the auxiliary hydraulics and fully lower the loader arms.
To relieve the pressure while the engine is off, move the auxiliary-hydraulics lever between the forward and reverse flow positions to relieve auxiliary hydraulic pressure, move the attachment-tilt lever forward and rearward, and move the loader-arm lever forward to lower the loader arms (Figure 34).

Hydraulic Tank Capacity: 62 L (16.3 US gallons)
Use only 1 of the following fluids in the hydraulic system:
-
Toro Premium Transmission/Hydraulic Tractor Fluid (refer to your Authorized Service Dealer for more information)
-
Toro PX Extended Life Hydraulic Fluid (refer to your Authorized Service Dealer for more information)
-
If either of the above Toro fluids are not available, you may use another Universal Tractor Hydraulic Fluid (UTHF), but they must be only conventional, petroleum-based products. The specifications must fall within the listed range for all the following material properties and the fluid should meet the listed industry standards. Check with your hydraulic fluid supplier to determine if the fluid meets these specifications.
Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendations.
